收到錯誤：運行咕嚕

Question

當我有一個在發展中的

yarn start

啓動了一個項目產卵./node_modules/.bin/grunt ENOENT它運行一個index.js啓動咕嚕過程，並得到這個錯誤：

$ yarn start 
yarn start v0.23.2 
$ node ./development 
grunt_arguments [ '--force', '--notify', '--verbose', '--debug', '--stack' ] 
======================================= 
Open http://localhost:8000 to start developing 

events.js:141 
     throw er; // Unhandled 'error' event 
    ^

不知道它是什麼。環境是：

運行我通常猴子補丁child_process幫我調試那樣的問題。加入這樣的事情在你index.js文件的開頭：

const util = require('util') 
const childProcess = require("child_process"); 

const originalSpawn = childProcess.spawn; 

childProcess.spawn = function() { 
    console.trace('SPAWN'); 
    console.log('ARGS'); 
    console.log(util.inspect(arguments, false, null)); // showHidden = false, depth = null 

    return originalSpawn.apply(this, arguments); 
}; 

如果你的跑步，childProcess.spawn('ls', ['-lh', '/usr'])，你會看到類似這樣的：

Trace: SPAWN 
    at Object.childProcess.spawn (repl:2:9) 
    at myFunction (repl:2:14)

    at REPLServer.Interface._onLine (readline.js:210:10) 
ARGS 
{ '0': 'ls', '1': [ '-lh', '/usr' ] } 

運行它後，也許你可以用新的信息來更新你的問題。
